Recreational Towing-Two Wheel Drive
Models
DO NOT flat tow this vehicle. Damage to the
drivetrain will result.
Recreational towing (for two-wheel drive
models) is allowed ONLY if the rear wheels
are OFF the ground. This may be accom-
plished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:
1. Properly secure the dolly to the tow ve-hicle, following the dolly manufacturer's
instructions.
NOTE:
If vehicle is equipped with Quadra-Lift air
suspension, ensure the vehicle is set to
Normal Ride Height.
2. Drive the rear wheels onto the tow dolly.
3. Firmly apply the parking brake. Shift the transmission into PARK.
4. Turn the ignition OFF.
5. Properly secure the rear wheels to the dolly, following the dolly manufacturer’s
instructions. 6. Install a suitable clamping device, de-
signed for towing, to secure the front
wheels in the straight position.
CAUTION!
Towing with the rear wheels on the ground
will cause severe transmission damage.
Damage from improper towing is not cov-
ered under the New Vehicle Limited War-
ranty.
Recreational Towing — Quadra-Trac I
(Single-Speed Transfer Case) Four-Wheel
Drive Models
Recreational towing is not allowed. These
models do not have a NEUTRAL (N) position
in the transfer case.
NOTE:
This vehicle may be towed on a flatbed or
vehicle trailer provided all four wheels are OFF
the ground.
CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case damage.
Damage from improper towing is not cov-
ered under the New Vehicle Limited War-
ranty.
Recreational Towing — Quadra–Trac

Models
The transfer case must be shifted into NEU-
TRAL (N) and the transmission must be in
PARK for recreational towing. The NEUTRAL
(N) selection button is adjacent to the trans-
fer case selector switch. Shifts into and out of
transfer case NEUTRAL (N) can take place
with the selector switch in any mode position.
CAUTION!
• DO NOT dolly tow any 4WD vehicle. Towing with only one set of wheels on the
ground (front or rear) will cause severe
transmission and/or transfer case dam-

age. Tow with all four wheels either ON
the ground, or OFF the ground (using a
vehicle trailer).
• Tow only in a forward direction. Towing
this vehicle backwards can cause severe
damage to the transfer case.
• The transmission must be in PARK for
recreational towing.
• Before recreational towing, perform the
procedure outlined under “Shifting into
NEUTRAL (N)” to be certain that the
transfer case is fully in NEUTRAL (N).
Otherwise, internal damage will result.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
• Do not use a bumper-mounted clamp-on
tow bar on your vehicle. The bumper
face bar will be damaged.
Shifting Into NEUTRAL (N)
WARNING!
You or others could be injured or killed if
you leave the vehicle unattended with the
transfer case in the NEUTRAL (N) position
without first fully engaging the parking
brake. The transfer case NEUTRAL (N)
position disengages both the front and rear
driveshafts from the powertrain and will
allow the vehicle to roll, even if the trans-
mission is in PARK. The parking brake
should always be applied when the driver
is not in the vehicle.
Use the following procedure to prepare your
vehicle for recreational towing.
CAUTION!
It is necessary to follow these steps to be
certain that the transfer case is fully in
NEUTRAL (N) before recreational towing
to prevent damage to internal parts. 1. Bring the vehicle to a complete stop, with
the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. If vehicle is equipped with Quadra-Lift air suspension, ensure the vehicle is set to
Normal Ride Height.
5. Using a ballpoint pen or similar object, push and hold the recessed transfer case
NEUTRAL (N) button (located by the se-
lector switch) for four seconds. The light
behind the N symbol will blink, indicating
shift in progress. The light will stop blink-
ing (stay on solid) when the shift to NEU-
TRAL (N) is complete. A “FOUR WHEEL
DRIVE SYSTEM IN NEUTRAL” message
will appear in the instrument cluster.

6. After the shift is completed and the NEU-TRAL (N) light stays on, release the NEU-
TRAL (N) button.
7. Shift the transmission into REVERSE.
8. Release the brake pedal for five seconds and ensure that there is no vehicle
movement.
9. Press and hold the brake pedal. Shift the transmission back into NEUTRAL.
10. Firmly apply the parking brake. 11. With the transmission and transfer case

14. Attach the vehicle to the tow vehicle using a suitable tow bar.
15. Release the parking brake.
NOTE:
• Steps 1 through 4 are requirements that must be met before pushing the NEUTRAL
(N) button, and must continue to be met
until the shift has been completed. If any
of these requirements are not met before
pushing the NEUTRAL (N) button or are
no longer met during the shift, then the
NEUTRAL (N) indicator light will flash
continuously until all requirements are
met or until the NEUTRAL (N) button is
released. • The ignition must be in the ON/RUN mode
for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indica-
tor lights will be on or flashing.
• A flashing NEUTRAL (N) position indica- tor light indicates that shift requirements
have not been met.
• If the vehicle is equipped with Quadra-Lift air suspension, the engine should be
started and left running for a minimum of
60 seconds (with all the doors closed) at
least once every 24 hours. This process
allows the air suspension to adjust the
vehicle’s ride height to compensate for
temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your
vehicle for normal usage.
1. Bring the vehicle to a complete stop, leav-
ing it connected to the tow vehicle.

TOWING A DISABLED
VEHICLE
This section describes procedures for towing
a disabled vehicle using a commercial towing
service. If the transmission and drivetrain are
operable, disabled vehicles may also be
towed as described under “Recreational Tow-
ing” in “Starting and Operating”.NOTE:
Vehicles equipped with Quadra-Lift must be
placed in Transport mode, before tying them
down (from the body) on a trailer or flatbed
truck. Refer to “Quadra-Lift” in “Starting and
Operating” for more information. If the ve-
hicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs must
be fastened to the axles (not to the body).
Failure to follow these instructions may cause
fault codes to be set and/or cause loss of
proper tie-down tension.

Four-Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of vehicle raised and the opposite
end on a towing dolly.
If flatbed equipment is not available, and the
transfer case is operable, vehicles with a
two-speed transfer case may be towed (in the
forward direction, with ALLwheels on the
ground), IFthe transfer case is in NEUTRAL
(N) and the transmission is in PARK. Refer to
“Recreational Towing” for detailed instruc-
tions.
Vehicles equipped with a single-speed trans-
fer case have no NEUTRAL position, and
therefore mustbe towed with all four wheels
OFF the ground.
CAUTION!
• Front or rear wheel lifts must not be
used. Internal damage to the transmis-
sion or transfer case will occur if a front
or rear wheel lift is used when towing.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
